| 摘 要： | 采用准静态近似理论方法分析简支圆板在平头弹丸正撞下的变形和穿透。首先基于虚功原理得到了静态荷载位移关系，并将其用于预测低速冲击下圆板的能量吸收能力。当考虑了材料的应变率敏感性，并且不发生绝热剪切冲塞破坏的前提下，理论预测和实验结果吻合良好。

| Abstract: | A previously proposed approximate quasi-static theoretical method is employed herein to examine the deformation and perforation of a simply-supported circular plate struck by a flat-faced projectile at normal incidence.Based on the principle of virtual work,static load-displacement relationships are first obtained and then used to predict the energy-absorbing capacity of the plate subjected to relatively low speed impact.It is shown that good agreement is obtained between the theoretical predictions and the available experimental data,provided that adiabatic shear plugging failure does not occur,but the influence of strain rate sensitivity is taken into account. |
